中文摘要：
为了延长无线传感器网络的生命周期,提高节点能量利用率,将分簇与节点调度相结合,提出了一种基于节点调度的双簇头的路由协议.该算法利用节点调度实现网络中冗余节点查找,减少分簇时活跃节点;考虑节点和基站的距离及能量,优化选择主、副簇头,副簇头优先选择冗余节点.主簇头用以收集和融合簇内节点的信息,副簇头负责与基站进行通信.仿真结果表明,新算法能有效节约网络能量、平衡节点能耗、延长网络生存时间.
英文摘要：
In order to prolong the lifetime of wireless sensor network （WSN） and improve the energy efficiency, a double cluster head routing protocol based on node scheduling method （DHCNS） for WSN was proposed by combining the techniques of cluster and node scheduling. In the algorithm the node scheduling was used to reduce the number of active nodes before clustering. The master and vice cluster-head were selected according to both on node energy and distance to base station and the redundant nodes were selected as the vice cluster-head in priority. The master cluster-head was used for collecting and integrating data. The vice cluster-head was in charge of transporting data to base station. The simulation results show that DHCNS can effectively reduce energy consumption, balance the energy of nodes, and prolong the network lifetime.
